1 Customer Review
Drugs across therapeutic indications induce lipid formation in hiPS-CM. Lipid accumulation was detected in cardiac cells using the LipidTox plate-based fluorescent assay on the Thermo Scientific CellInsight High Content platform. A) Ten drugs increased lipid levels in hiPS-CM following 48 h treatment. The lowest drug dose that induced a N1.5-fold increase in lipid formation is shown. B) Representative images (20×) from the assay are shown to the right. All drugs had >55% cell viability at 48 h at these tested concentrations. C) Of these 10 drugs, 8 significantly increased lipid accumulation following only 24 h treatment (images not shown). All drugs had >80% cell viability at 24 h at these drug doses. The graphs represent the mean fold-change of the lowest concentration of drug that significantly induced lipid formation >1.5-fold more than vehicle control. *P<0.05, **P<0.01, and ***P<0.0001.

|Description||Amiodarone HCl is a sodium/potassium-ATPase inhibitor and an autophagy activator, used to treat various types of cardiac dysrhythmias.|
Amiodarone possesses an inhibitory effect on the fast sodium channel as well as on the slow calcium channel. Amiodarone also has non-competitive antisympathetic effects, and modulates thyroid function and phospholipid metabolism. Amiodarone penetrates deeply into the lipid matrix of the membrane, and is released from cardiac tissues very slowly when washed out. Amiodarone (44–88 μM) depresses Vmax of guinea pig papillary muscle without affecting the resting membrane potential, and that this Vmax inhibition is enhanced in a frequency- or use-dependent manner like Class I antiarrhythmic drugs. Amiodarone (50–88 μM) is also found to suppress the depolarization-induced spontaneous action potentials (abnormal automaticity) in ventricular muscles and in Purkinje fibers. 
|In vivo||Amiodarone (1.25–25 mg/kg) results in a decrease in sinus rate, a prolongation of effective and functional refractory periods of the atrioventricular node, and a frequency-dependent conduction delay in the atrioventricular node and in the ventricle of anesthetized dogs. Amiodarone (50 mg/kg/day, i.p. for 3–4 weeks) results in significant decreases in the current density of iK and ito in ventricular cells without affecting iCa and iK1 densities in rabbit. Amiodarone (AM) inhibits intracellular conversion from thyroxine (T4) to triiodothyronine (T3) via 5′-deiodination (5′DI) without affecting intracellular conversion from T4 to reverse T3 (rT3). |

|Ethanol||11 mg/mL (16.13 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
2% DMSO+30% PEG 300+2% Tween 80+ddH2O
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
